A visual AQI tutorial

This is the view from our bedroom window at the same time under similar weather forecast conditions (clear and sunny). On the left, a 300 AQI reading. On the right, a 70 AQI reading. When the AQI reading is under 30, you can see the mountains behind that farthest building. When the AQI is over 350, you can not see the houses past the black cars.
